Of the total number of flats, around 10,000 unoccupied ones are from the 2014 housing scheme, while 2,000 have been lying vacant.

The 2017 housing scheme, which offers the 12,000 flats, ranging from close to Rs 7 lakh to over Rs 1.26 crore, was launched on June 30.

After the closure of the extended deadline for submission of forms, about 90,000 forms were sold. "The deadline ended on September 11 and the total number of applications received stand at over 46,000. The last date for applying for any rectification in forms ended on November 10," said a DDA official said.

DDA's Principal Commissioner (Housing) J P Agarwal said the DDA wants genuine people to apply and ward off market speculation.

The DDA has made every possible effort to address all concomitant issues, including water supply and transportation, Agarwal said.

The 2014 scheme offered 25,040 flats across categories, with prices ranging between Rs 7 lakh and Rs 1.2 crore. The online response was so massive that the DDAs official website crashed soon after the launch. The one-bedroom flats were offered in Dwarka, Rohini, Narela and Siraspur areas.
